INTERNAL-COMBUSTION ENGINE.

Application filed January 20, 1920. Serial No. 352,772.

To all to 710m it may concern Be it known that I, lVALTnn J. BAUM- cAnrNnn. a citizen of the United States, residin in Brooklyn, in the county of Kings and t tate of New York, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification. 7 V

I have invented an improvement relating to internal combustion engines and comprising an operating connection for a governor designed to regulate and control the engine by limiting the speed of same.

An object of my invention is to provide a device which is adapted to connect the governor of an internal combustion engine with a movable part of the engine capable of driving the governor, and which can be easily and conveniently installed without material alteration of the engine or important arts thereof.

A further object of my invention is to provide a device which can be utilized to put such a governor into operativerelation with an lnternal combustion engine, and which 18 so constructed that it can cause the governor to be actuated from the cam shaft of the engine whether or not the latter is provided with an electrical generator of the type commonly used for starting and lighting.

Other objects and advantages of my invention are set forth in the following speciiication, taken with the accompanying drawings, which present the best embodiment of my invention now known to me. This disclosure, however, is explanatory only and I reserve the right to resort to changes not illustrated herein, but nevertheless within the scope and spirit of my invention as the same is indicatedby the general meanings of the terms in which the claims are expressed, and by variations of phrase specifying the novel featuresthat the claims set forth.

In the detailed description of the construction which is outlined in, the figures above mentioned, the numeral 1 is employed on Figures 1 and 2 to indicate an in ternalcoinbustioii engine for a motor vehicle, such as a commcrical truck. This engine has an intake manifold 2 to which a fuel supply conduit 8 leads from a carbureter &. Between the carbureter and the intake manifold is a governor in a casing 5; this governor comprising a. throttle valve .controlled by centrifugal wei hts to diminish the flow of fuel to the engine when the latter reaches a pre-determined speed and to shut oft" the gas entirely as soon as that speed is exceeded. The weights are caused to re volve by a spindle passing through tubular sleeve 6 and connected to the cam shaft of the engine 1, as will be described pres ently. The engine 1 also has a top or head 7, and an exhaustmanifold and all other necessaryparts, not appearing on the draw ings because they do not need to be shown herein. The carburetor 41 is of any approved type and the governor in the casing 5 is also well-known and doesnot need to be further described.

The engine 1 has a cam shaft indicated at 8 in Figure 2', extending lengthwise of the same; and it carries the usual half-timegear indicated at 9 thereon. This gear-9 is driven from the crank-shaft 10; and, as usual in this type of engine, the frontend of the shaft 9 actuates thetimer mechanism,

which. is enclosed by the casing '11. The shaft 8,besides operating the cams for the valves of the engine and the timerinechanism, is connected to rotate gearing in a support or housing 12. This .iousing adapted to be readily attached to the engine by securing screws It is held in place at one side of the engine, near the front end of the same, and on its rear lace can be mounted an electrical generator 11 by means of screws 15. This generator is oi? the type commonly used for starting. lighting and other purposes and is held fast by the screws 15, which extend through the support 12- lengthwise ot the engine and serve not only to hold the generator but also to secure to the front of the housing a plate 16. The outline of this plate is indicated in Figure 2 and it serves to close a portion of the front of the engine and to carry the timer casing 11. From the upper part of the support 12 there extends, in a rearward direction, the tubular sleeve (3, which houses the shaft to drive the governor in the casing The plate 16, further. carries the oil-tiller spout l7, through which luln'icant tor the interior of the engine 1 admitted.

The support 12 is preferably made up in one piece by casting: although. of 'oii"-", other methods oitmakingit can be employed. its lower portion 18 serves as a bracket for mounting the generator 14, and this bracket is therefore open in the front. at the rear and at one side so that it can communicate with the inside of the engine 1. See Figures 3, 1, 5 and 6. On the interior of this bracket is a gear 19 which meshes with the gear 8 and is adapted to operate the generator let when such a generator is present. The support 12 also comprises an extension 20, on top of the bracket 18. containing gears 21, 22 and 23. The gear 21 meshes with the gear 19 and is mounted on the same shaft as the gear 22; this sha'tt being in dicated by the numeral. 2%, and. beii'ig 1nounted in hearings in the front and rear faces of the extension 20. The gear 22 meshes with gear 23 in the extension 20, and this gear 23 is carried. by a shaft or spindle said shaft 25 being carried in hearings in the front and rear -faces of the extension and joined to the end 26 of a shaft in the tubular sleeve 6 for the governor in the casing 5. The side of extension 20 which is away from the engine may be open and provided with a removable cover 2? so as to give ready access to the above mentioned The support 12 with the gears therein is adapted for ready attachment to the engine in place of a bracket 28 which ordinarily mounts" the generator is. This bracket 28 is shown in Figures 8 and 9 and has the same shape as the bracket 18 without the extension 20, It is closed in front by the plate 16 and carries the generator 14 by having the latter made fast to its rear face by means of the bolts or screws 15, passed as before, through both the bracket and the plate 16. It is held to the side of the engine by means oi screws .13. Hence, to move this bracket, the screws 15': are iii-st taken out and then the screws 13, so as to permit the sepa ration of the bracket and the generator and the removal of the bracket tron] the engine. The bracket of be support 12 can then be si'ibstituted by aching he lower part 11 to the engincin the same manner as when the bracket 28 is used: and the generator is mounted on the rear face ot the bracket 13 of the support 12 by replacing he belts or screws 7. When the engine is in operation the gear 8 turns the gear 1) to run the gener- Mo and the gear it) acts through the gears above it to turn the shaft 253. in case there is no generator on the engine, the rear end oi? the brar t 18 wilt be closed by a plate after re eiving inside oi? it, a bearin rblock 30, in which is mounted a. carrying gear 19; and the governor can he then operated the same as when the generator is present.

ifhen the generator is present, the rut-out be): which is usually mounted thereon can be ren'ioved and mounted on the dash-board. This cut-out box is indicated at 32 in Figure 10. One terminal will be grounded as by the wire 32 and the wire ordinarily used running from the dash to the generator ca be cut to make new connections.

My invention is primarily adapted for engines on trucks. The engine 1 is oi? a wellknown design. To install my governor connection, one proceeds first to disunite one cable at the battery, it a generator is present. Then the hood on the carburetor side is opened and the generator dismounted by taking out the screws 15. If no generator is present, 0t course, the operation is simpler. The generator bracket 28 shown in Figures 8 and 9 is then dismounted by taking out the bolts 13. Then the support 12 is attached to the engine in the same posi tion as the bracket 28, the screws 13 being replaced for this purpose. The generator 11: is then bolted. to the rear face oi the bracket 18 oi? the support 12 by the screws 15, pass ing as before through the plate 16 and the bracket 18. If there is no generator on the motor or engine, the plate 29 with the hearing block 30 therein is fastened to the rear face 015 the bracket 18. The cut-out box 32 is removed from the generator, fastened to the dash, and one terminal ground as above stated. IText the regular intake manifold, not shown, is separated from the engine 1, and the manifold 2 is substituted, the manitold having fastened thereto the casing 5, the elbow 8, and the carburetor t; making a complete unit. The shaft of the governor is inserted into the end of the shaft 25 and into the sleeve 6, which is already attached to the support 12; and the manifold 2 is made fast.

The motor is then properly equipped With spindle 31 a governor and operates as before, with or without the generator 14, and no other change in the structure of the engine is re quired to mount the governor thereon and thus secure proper control of the engine speed. The governor is adjacent the support 12 but a little above and tothe rear of the generatorl l, when arranged as shown in Figure l, but obviously other relative positions may be selected, so long as the nature of the invention is not changed.

Of course the plate 29 and block 30 may be in one piece and such a construction in fact is preferable.

Having described my invention, what I believe to be new and desire to secure and protect by Letters Patentv of the United States is ljAn attachable support or housing shaped to enable it to be secured to an engine, said housing comprising a bracket, said bracket being shaped to mount an electrical generator 011 the back thereof and to be covered by a plate in front, said support also being open at one side to communicate with the interior of the engine, an extension on the top of saidbracket, and gears in said extension to operate a shaft extending therefrom.

2. A support adapted to be secured to an engine, the support having a bracket open at one side to communicate with the in side of the engine, the bracket being shaped to support a generator at the back and to be covered by a plate in front, an extension on top of said bracket, gears in said extension to rotate a shaft extending therefrom, said extension having an opening, and a removable plate to close said opening.

3. An attachable support or housing shaped to enable it to be secured to an engine, said housing comprising a bracket, said bracket being open in front and back, and being shaped to mount an electrical generator on the back thereof and to be closed by a plate in front, saidsupport also being open at one side to communicate with the interior of the engine, an extension on the top of said bracket, and gears in said extension to operate a shaft extending therefrom.

4. A support adapted to be secured to an engine, the support having a bracket open in front and back, and at one side to com municate with the inside of the engine, the bracket being shaped to support a generator at the back and to be closed by aplate in front, an extension on top' of said bracket, gears in said extension to rotate a shaft ex tending therefrom, said extension having an opening, and a removable plate to close said opening.

In witness whereof, I have signed my name to this specification this 19th day of December, 1919.
